Radar-jamming System Simulation

The electronic war is playing more and more important role in the modern war.And the electronic jamming is one of the important techniques in the flied of theelectronic countermeasure. This paper has mainly researched techniques about theradar system countermeasure technology.Firstly, this paper has mainly discussed the active jamming system and thedeception jamming system, and made some research about the two main parts whichare the design of the jamming techniques and power management system. In the firstpart, the emphasis is played on research of the radio noise system, amplitudemodulation system and frequency modulation system. And discussed the productionof some kinds of jamming signals, also made some simulations, in addition, theproper jamming systems has been designed and analyzed. In the second part, thepaper has discussed the methods about the production of the deception jammingsignals from the distance deception jamming system, speed deception jammingsystem as well as the angle deception system, in addition, the frame of the jammingsystems are given and some analysis are made.Secondly, the paper has mainly made some research about the two keytechniques which are digit radio frequency memory techniques and the frequencyleading techniques in the radar jamming system. In the first part, some simulationsare made about the its principle, and the paper has analyzed all kinds of the parasiticsignals according to method of the amplitude quantization. The result indicated thatthe affect of the parasitic signals could be neglected when number of the quantizationis not less than eight. On the basis of the frequency leading techniques at presents, thepaper has discussed a new method which includes DIFM, digit frequency leading anddifference frequency leading technology. The result indicated that this techniques hasthe quick leading time and high leading precision.The paper has also discussed a algorithm of radar jamming resources assignmentbased on the Operation Research in the field of the power management system. Theresult of the simulation indicated that this algorithm is feasible and efficient, it alsohas some advantages over other algorithms.At last, the paper designed a system which was used in the emulators about theactive jamming system and the deception jamming system. and made someexperiments about the production of various jamming signals included barragejamming signal, distance deception jamming signal speed deception jamming signal.
